exchange.IO("lp.pool", ...)

Read the live state and statistics of a concentrated-liquidity pool.

    
    
    
exchange.IO(k, poolId)

Examples

Read a pool and derive the price from the current bin or tick.

    javascript
    
    
function main() {
    var sel = exchange.IO("lp.select", "SOL", 100, {quote: "USDC"})
    if (!sel) {
        Log("Selection failed:", GetLastError())
        return
    }
    var p = exchange.IO("lp.pool", sel.protocol + ":" + sel.id)
    if (!p) {
        Log("Read failed:", GetLastError())
        return
    }
    var scale = Math.pow(10, p.decimalsX - p.decimalsY)
    var calc = p.protocol == "meteora"
        ? Math.pow(1 + p.binStep / 10000, p.activeId) * scale
        : Math.pow(1.0001, p.tick) * scale
    Log(p.dex, p.symbolX + "/" + p.symbolY, "price", p.price, "derived", calc)
    Log("reserves", p.reserveX, p.symbolX, p.reserveY, p.symbolY, "24h fees", p.fees24hUsd)
}

Remarks

X and Y follow the pool's own token order: price is the Y value of one X, and reserveX and reserveY are the pool's balances of the two tokens. lp.pools converts to base and quote tokens around the token queried, lp.pool does not; for a quote-per-base price, check the orientation with symbolX and symbolY. An empty pool has price 0.

Fields by protocol

See exchange.IO("lp.pools") for their meaning and the form of rewards.

Price and index: the price of DLMM bin i is (1 + binStep/10000)^i, that of Raydium or Orca tick i is 1.0001^i, both multiplied by 10^(decimalsX − decimalsY) for readable units.
